## What is the definition of a coordinate plane?

A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called y-axis and a horizontal line called x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin.

## What is the definition of coordinates for kids?

Coordinates are a set of numbers or numbers and letters together that show you a position on a map. They can help you find a specific place or object that you are looking for. Coordinates are written in parentheses and separated by a comma: (H, 4). Take a look at the map on this page.

**Why is it called a coordinate plane?**

Tanish J. The invention of the Cartesian Coordinate System is credited to René Descartes. He revolutionised mathematics by providing the first systematic link between Euclidean geometry and algebra. Thus, the Coordinate Plane is named after him.

**What is coordinate in graph?**

Coordinates are numbers which determine the position of a point or a shape in a particular space (a map or a graph).

### What is a coordinate graph?

A coordinate graph is a set of two number lines that run perpendicular to one another. These number lines are called axes. The horizontal number line is the x-axis, and the vertical number line is the y-axis. The two axes intersect where each of them are equal to zero, and this intersection point is called the origin.

### How do you graph a coordinate plane?

When you’re graphing a point on the coordinate plane, you will graph it in (x, y) form. Here is what you’ll need to know: The x-axis goes left and right, the second coordinate is on the y-axis. The y-axis goes up and down.

**Why do we use coordinate planes?**

The coordinate plane can be used to plot points and graph lines. This system allows us to describe algebraic relationships in a visual sense, and also helps us create and interpret algebraic concepts.

**How do you do coordinates?**

Coordinates are written as (x, y) meaning the point on the x axis is written first, followed by the point on the y axis. Some children may be taught to remember this with the phrase ‘along the corridor, up the stairs’, meaning that they should follow the x axis first and then the y.
